--------------------------------------------

             Summary: Invalid validation of coprocessor whitelist
                 Key: HBASE-20735
                 URL: https://issues.apache.org/jira/browse/HBASE-20735
             Project: HBase
          Issue Type: Bug
          Components: Coprocessors
            Reporter: Jagadeesh Anabathula


Per HBASE-16700, coprocessors can be present only in whitelisted paths.
 It validates for every new coprocessor, if jar's path is in whitelist paths.
 It is currently validating only the first coprocessor that is set to a table. All the coprocessors that are added after that are not validated and allows path other than that are whitelisted.

In my case, I have hbase.coprocessor.region.whitelist.paths as /tmp/**,*/tmp/coprocessors/*

Following works fine
 hbase(main):001:0> create 'test_coprocessors', 'c'
 0 row(s) in 1.7540 seconds

=> Hbase::Table - test_coprocessors
 hbase(main):002:0> alter 'test_coprocessors', METHOD => 'table_att', 'COPROCESSOR' => 'hdfs:/tmp/coprocessors/coprocessors-0.4.0.jar|com.bloomberg.hbase.coprocessors.observers.PrefixedDataFilter|100|prefix=P'
 Updating all regions with the new schema...
 1/1 regions updated.
 Done.
